I've herd of that happening. You should have tracked him down and removed his radio with a ball peen hammer!
And he was broadcasting with normal voltage, otherwise the whole vehicle would have shorted out. He was most likeky using a linear amplifier to increase the WATTAGE. Mobile Citizen Band radios are set to broadcast at 4 Watts maximum. With an linear amp, Mr. Jerk was probably pumping out 50W, although 100W-250W is not unheard of, with the right antenna.
